The dust collection box 1 has a suction hole 3 and a discharge hole 4, and the vacuum device 2 is connected to the discharge hole 4. The dust collection box 1 is connected to the wallboard 5 of the printing press, and the suction hole 3 corresponds to the printing substrate 6 in the printing press, so that the vacuum device 2 can suck the dust on the printing substrate 6 into the dust collection box 1. With such a technical solution, the dust attached to the surface of the printing substrate can be removed, thereby ensuring the printing effect. In actual production, along the running direction of the printing substrate 6, the dust collection box 1 is located upstream of the printing roller of the printing press, so that the printing roller can print on the cleaned printing substrate 6.

[0028] Furthermore, if Figure 1 As shown, it also includes a first metal mesh 7, a second metal mesh 8 and a high-voltage pulse power supply 9; the first metal mesh 7 and the second metal mesh 8 are both fixedly connected in the suction hole 3, and the first metal mesh 7 and the second metal mesh 8 are spaced apart in a direction away from the printing substrate 6. The high-voltage pulse power supply 9 is fixedly arranged in the dust collection box 1, and the positive electrode is connected to the first metal mesh 7, and the negative electrode is connected to the second metal mesh 8. In this way, an electrostatic field can be formed on the first metal mesh 7 and the second metal mesh 8, and then the dust on the surface of the printing substrate can be cleaned by electrostatic adsorption. In the specific production, the first metal mesh 7 and the second metal mesh 8 are parallel to each other, and the distance between the two is 200mm to 300mm.

[0029] As an implementation method, Figure 1 , 2As shown, it also includes a connecting pipe 10, and the vacuum device 2 is fixedly connected to the wall panel 5 and connected to the discharge port through the connecting pipe 10. The connecting pipe 10 can be a retractable hose, and the vacuum device 2 can be a vacuum pump.

[0030] The following is a detailed introduction to the connection between the dust collection box 1 and the wall panel 5:

[0031] like Figure 2 As shown, the dust collecting box 1 also includes a driving device and a slider 12, the dust collecting box 1 is fixedly connected to the slider 12, the slider 12 is slidably connected to the wall panel 5, and the driving device is in transmission connection with the slider 12 to drive the slider 12 to drive the dust collecting box 1 to approach or move away from the printing substrate 6. In this way, the distance between the dust collecting box and the printing substrate 6 can be adjusted according to actual needs, thereby improving the cleaning effect of the dust on the printing substrate 6.

A screw hole 16 matching the threaded section 15 is provided on the slider 12. The positioning plate 13 is fixedly connected to the wall panel 5. The driving rod 11 is rotatably connected to the positioning plate 13 through the mounting section 14, and is threadedly connected to the screw hole 16 through the threaded section 15, so that the slider 12 is driven to move by screwing the threaded section 15 in or out of the screw hole 16. Specifically, as Figure 2 As shown in the figure, the positioning plate 13 is provided with a mounting hole 17, the mounting section 14 is shoveled into the mounting hole 17, and a circular positioning protrusion 18 is provided on the outer wall of the mounting section 14. The positioning protrusion 18 is located on the side of the positioning plate 13 facing away from the slider 12. This ensures that the relative position between the driving rod 11 and the positioning plate 13 will not change. In actual production, Figure 2 As shown, a hand wheel 19 is also included, and the hand wheel 19 is fixedly connected to one end of the mounting section 14 away from the threaded section 15. In actual use, the operator can drive the driving rod 11 to rotate through the hand wheel 19.
